'Impeachment is about Trump’s conduct, not mine': Biden expands on subpoena remarks

Former vice president and Democratic presidential candidate Joe Biden looked to clarify his remarks about complying with congressionally issued subpoenas in a series of tweets on Saturday morning.

Biden said he cooperated with all "legitimate congressional oversight requests" in his 40 years in public life but argued there was no "legal basis for Republican subpoenas for my testimony in the impeachment trial."

"The subpoenas should go to witnesses with testimony to offer to Trump’s shaking down the Ukraine government — they should go to the White House," Biden added.

During a Friday interview with the Des Moines Register's editorial board, Biden said he would not comply with a Senate subpoena during President Donald Trump's impeachment trial in the Senate.

House Democrats passed two articles of impeachment against Trump on Dec. 18 for abuse of power and obstruction of Congress, but have delayed the transmission of the articles to the Senate until senators come to an agreement on a Senate trial.

Democratic and Republican senators, however, are currently at what Senate Majority Leader Mitch McConnell, R-Ky., described as an "impasse" over negotiations on the format for a Senate trial.

Democrats want to be able to call documents and witnesses who declined to comply during the House's impeachment inquiry like former national security adviser John Bolton and Office of Management and Budget official Michael Duffey.

Some Republicans, on the other hand, have floated the possibility of calling Biden or his son Hunter Biden during the Senate trial.
